Call me paranoid, but I prefer to keep my private information - private; that includes my picture and my likeness. Even when I did have an account, I never kept a picture on there and hated when people tagged me in theirs. I removed the tags immediately. In the same way Jason likes to keep his public and private pictures separate (#24), I prefer to keep all my pictures private.
As it turns out, I left not a moment too soon. Facebook recently updated their TOS so that they now own the rights to all your information, pictures, and even your name forever and ever to use in whatever way they want.
You hereby grant Facebook an irrevocable, perpetual, non-exclusive, transferable, fully paid, worldwide license (with the right to sublicense) to (a) use, copy, publish, stream, store, retain, publicly perform or display, transmit, scan, reformat, modify, edit, frame, translate, excerpt, adapt, create derivative works and distribute (through multiple tiers), any User Content you (i) Post on or in connection with the Facebook Service or the promotion thereof subject only to your privacy settings or (ii) enable a user to Post, including by offering a Share Link on your website and (b) to use your name, likeness and image for any purpose, including commercial or advertising, each of (a) and (b) on or in connection with the Facebook Service or the promotion thereof.
They can even license it to 3rd parties. So my dear friends, please do not post anymore pictures of me to your facebook accounts. Hell, I'd prefer if you didn't post them to anywhere online. If you love looking at me so much, keep me to yourselves please. I would hate to be the guy whose face is unwittingly used to advertise the next erectile dysfunction drug or something like that.
